Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to various imaging devices such as cameras, and particularly relates to the position of a release operation member in the imaging device.

[Prior Art] FIG. 2 is a perspective view schematically showing a single-lens reflex camera or a so-called compact camera as a conventional imaging device.
21 is a camera body, 22 is a photographic lens, 23 is a finder window, 24 is a grip for holding the camera, 2
5 is a release button. Further, the arrow in the figure indicates the direction of incidence of the photographing light.

As shown in Figure 2, this type of camera holds the camera by applying forces in a plane perpendicular to the photographic optical axis, and then releases the camera in a direction approximately perpendicular to the direction of these forces using the index finger that is not involved in holding the camera. The configuration is such that the button 25 is operated, and the configuration is such that hand shake (hereinafter referred to as camera shake) is unlikely to occur during the release operation.

Next, FIG. 3 is a perspective view schematically showing a conventional video camera. In Fig. 3, 31 is the camera body, 32 is the photographing lens, 33 is the finder's confinement lens, 34 is the grip for holding the camera, 35 is the strap for fixing the palm of the hand holding the camera, and 36 is the release button. It's a button. In addition, the arrow in Figure 1 indicates the incident direction of the photographing light. In a camera like the one shown in the figure, force is applied in a direction almost perpendicular to the optical axis, and the camera is held with the palm and fingers, and the thumb, which is not involved in holding the camera, is used to The release button 36 is configured to be operated in the direction of the optical axis, which is substantially perpendicular to the force applied to hold the camera, so that camera shake associated with the release operation is less likely to occur.

FIG. 4 is a perspective view schematically showing a conventional disc camera, in which 41 is a camera body, 42 is a photographing lens, 43 is a finder window, and 44 is a release button.

The arrow in the figure indicates the direction of incidence of the photographing light. In the camera shown in FIG. 4, press the back of the camera body 41 with your thumb (the surface opposite to the surface where the photographic lens 42 is located), and use your other fingers to press the front surface of the camera body 41 (the surface where the photographic lens 42 is located). Press to hold the camera. Release operation is on camera body 4
The direction of this operation is almost the same as the direction of the force applied to hold the camera, and the camera tends to move with the release operation.However, the direction of movement is based on the shooting optical axis. , and the configuration is such that camera shake is unlikely to appear on the photographic film. However, cameras using 110 cartridges are prone to camera shake.

FIG. 5 is a perspective view schematically showing a camera using a conventional 110 cartridge, in which 51 is the camera body, 52 is a photographing lens, 53 is a finder window, and 54 is a release button. Note that the arrow in the figure indicates the direction of incidence of the photographing light.

In a camera like the one shown in FIG. 5, you can press the camera body 51 with your thumb.
Hold the camera by pressing the bottom surface of the camera body 51 (the surface opposite to the surface where the release button 54 is located) and using your other finger to press the top surface of the camera body 51 (the surface where the release button 54 is located). For the release operation, the user presses the finger release button 54 located on the -E surface of the camera body 51. At this time, the direction of the force applied for the release operation is substantially the same as the direction of the force applied to hold the camera, and camera shake is likely to occur due to the release operation. Further, this direction is approximately perpendicular to the photographing optical axis, and the configuration is such that camera shake is likely to occur on the film surface.

Recently, a so-called still video camera that records images on a floppy disk (magnetic disk) has been put into practical use, but in order to make the camera more compact, the camera lens and finder optical system are placed parallel to the video floppy disk. is advantageous.

FIG. 6 is a perspective view schematically showing a conventional electronic still camera. In FIG. 6, 61 is a camera body, 62 is a photographing lens, 63 is a finder window, and 64 is a release button.

Further, 65 is a lid for taking in and out a floppy disk (not shown) into and out of the camera body 61, and an operation lever 66
The arrow in the figure indicates the direction of incidence of the photographing light.

In the camera shown in FIG. 6, the outer diameter of the floppy disk jacket is approximately 55 mm x 60 mm, so the length in the direction of the photographing optical axis is larger than that of the camera using the 110 cartridge film. In the camera shown in FIG. 6, as in the camera shown in FIG. Hold the camera by pressing the top surface (the surface where the release button 64 is located). For the release operation, the user presses the finger release button 64 located on the top surface of the camera body 61.

Therefore, like the camera shown in FIG. 5, the direction of the force applied for the release operation is substantially the same as the direction of the force applied to hold the camera, and camera shake is likely to occur due to the release operation.

This direction is substantially perpendicular to the photographing optical axis, and the configuration is such that camera shake is likely to appear on the image sensor (not shown). Furthermore, as described above, since the length of the camera body 61 in the direction of the photographing optical axis is longer than that of the camera shown in FIG. 5, the configuration is more likely to cause camera shake.

[Question 8 to be solved by the invention] As described above, a camera in which the camera is held in a direction substantially perpendicular to the photographing optical axis with a hand or finger has the disadvantage that camera movement is likely to occur due to the release operation.

The present invention was made to solve such problems, and an object of the present invention is to provide an imaging device that does not cause camera shake.

[Means for Solving the Problems] In order to achieve the above object, the imaging device of the present invention performs imaging. The release operating member is disposed on the first surface that has a fulcrum for holding the camera.

[Function] The present invention makes it difficult for camera shake to occur by performing a release operation on a surface having a fulcrum for holding a camera, which is an imaging device.

Embodiment FIGS. 1(a), 1(b), and 1(c) are a top view, a side view, and a bottom view, respectively, of a camera showing an embodiment of the present invention.

In Fig. 1, l is the camera body, 2 is the photographing lens, 3 is the eyecup attached to the finder eyepiece for observing the subject image, and 4 is the release button located on the bottom surface of the camera body l as a release operation member. be. la, l
b is located on the release button 4 or on the underside of the camera body l, so the release button 4 is likely to be pressed inadvertently when the camera is placed down, so this is a convex part to prevent this. 0The arrow in the figure indicates the shooting light indicates the direction of incidence.

According to the above configuration, the camera is held by supporting the bottom surface of the camera (the surface where the release button 4 is located) with the thumb and pressing the top surface of the camera (the surface opposite to the surface where the release button 4 is located) with the other fingers.

The direction of the force for the release operation is the direction in which the thumb or the release button 4 is pressed, which is approximately the same as the direction of the force for halting the camera, and is also approximately perpendicular to the photographing optical axis. However, the thumb is a fulcrum for holding the camera, and the force applied to release the camera does not act as a force to rotate the camera. Therefore,
Camera shake is extremely unlikely to occur.

[Effects of the Invention] As explained above, in the present invention, since the release operation member is disposed on the same plane as the fulcrum for holding the camera body, camera shake due to the release operation is less likely to occur.
